name: Extend
description: Extend is a product and shipping protection platform for merchants and ecommerce brands. Its API lets merchants
  surface extended-warranty and shipping-protection offers at checkout and post-purchase, create and manage protection contracts,
  process orders and line items, file and track claims, and manage service orders, refunds, and leads. Extend provides separate
  demo (sandbox) and production environments, header-based date versioning, OAuth2 client-credentials authentication with
  short-lived access tokens, idempotency keys on writes, and webhooks for claim and service-order status changes, alongside
  client-side SDKs and prebuilt commerce-platform integrations for Shopify, BigCommerce, Magento, WooCommerce, and Salesforce
  Commerce Cloud.
